Everything works with the AC, lighting, climate control adjustment, front & rear air, and it blows nice and cold, but when I shut the engine off, the fan is still running. I see from other threads that going to kill my battery soon, so hopefully someone has a fix for this issue.

Well that didn't take to long, about 10 hours and the battery is dead. Atleast my wife was at home when it died. A neighbor helped her jump start the X5 but I made sure they removed the fuses for the Air Conditioner, and fuses 75 and 76 for the Air Blower.

Fuses 75 and 76 are large fuses 30 and 40 Amp, that connects to relays to the Climate Control. The 30Amp Fuse is utilized when the Climate Controls are the halfway position and lower. When the Climate Controls are in positions higher than half then the power is routed to the 40 Amp Fuse and different relays.

It could be the bad FSU, but it sounds more like a relay issue. Tomorrow I will take it to an Air Conditioner Specialist and see how much it going to break me.
